Aortic Stenosis

Valve Does Not Open Fully

Aortic stenosis occurs when your aortic valve becomes thick, stiff and narrowed, causing it not to open fully.

Blocks Blood Flow

The result is obstruction or blockage of blood flow through this valve.

Ranges from Mild to Severe

Aortic stenosis ranges from mild to severe.

  • As the valve becomes narrower, more problems can occur.
  • The narrower it becomes, the harder the heart must work to pump sufficient blood with each beat.
